Customized implant abutments: technical notes

Custom-fabricated angulated abutments can be of value when implant angulation or position jeopardizes esthetics and/or function and makes retrievability difficult. A wax pattern is prepared over a castable pattern or gold cylinder. After the casting is completed, a secondary screw channel is created in the angulated abutment to retain the superstructure and the definitive prosthesis. The rationale for the use of customized angulated abutments is described. Technical procedures are presented that allow for modifications of individual cases.
